Alloy dental material Wirobond® C+

cobalt-chromiumfor dental restorationsfor implant abutments

Product overview
Wirobond® C+ is a cobalt-chrome dental alloy manufactured for Selective Laser Melting (SLM) applications. The material is formulated and processed to provide a homogeneous, highly dense microstructure suitable for ceramic veneering.

• Material: cobalt-chrome alloy optimized for dental restorations
• SLM production ensures dense, homogeneous structures compatible with veneering ceramics (with appropriate CTE)
• Controlled manufacturing for stress-free frames and high accuracy of fit
• Nickel- and beryllium-free to reduce cytotoxic and allergic risks

Indications

• Frameworks for partial and full veneered restorations up to 16 units with up to four pontics
• Fully anatomical crowns and bridges up to 16 units with up to four pontics
• Two-piece abutments
• Tertiary frames for crowns and bridges
• Retention per segment
